Title
(EN) A MACHINE VISION METHOD AND SYSTEM
(FR) PROCÉDÉ ET SYSTÈME DE VISION ARTIFICIELLE
Abstract
(EN)
The invention relates to a method, comprising capturing an image of an object to be monitored at a first image capturing frequency by an image sensor of a machine vision system, transmitting said captured image data to an image data processing device and analysing said received image data by said image data processing device, and wherein if the image data is detected to comprise a deviation, a trigger signal is transmitted for triggering an image sensor for reconfiguring it to capture an image burst and for transmitting the captured image burst data to said image data processing device for further analysis. The invention further relates to a machine vision system and a computer program product performing the method.

L'invention concerne un procédé comprenant la capture d'une image d'un objet à surveiller à une première fréquence de capture d'image par un capteur d'image d'un système de vision artificielle, la transmission desdites données d'image capturées à un dispositif de traitement de données d'image et l'analyse desdites données d'image reçues par ledit dispositif de traitement de données d'image, et, s'il est détecté que les données d'image comprennent un écart, un signal de déclenchement étant transmis pour déclencher la reconfiguration d'un capteur d'image pour qu'il capture une rafale d'images et la transmission des données de rafale d'images capturées au dit dispositif de traitement de données d'images pour une analyse ultérieure. L’invention concerne en outre un système de vision artificiel et un produit de programme informatique mettant en œuvre le procédé.
